Important keywords that we look out for

1)Temperature/ Water level has increased/decreased. (advisable to use this for tests and examinations)

2) Colder (object) gains heat from warmer object which is at a higher temperature.

I need to see the:

·        *direction of heat flow( from ____ to _____)

*difference in temperature

________gains heat from ______ at a higher temperature
_________ lost heat to_________ at a lower temperature

Activity 18
Topic: Expansion and contraction of a solid

Q2(b)How has the ball changed?
The ball has become bigger. It has expanded.

Q3(b) How has the ball changed?
The ball has become smaller. It has contracted.

You have to tell me how it has changed in terms of its size. We are also looking out for the terms "expanded" and "contracted" here in this topic.

Activity 19
6(a) What happened to the balloon?
The balloon was filled with more air and got inflated.
(You need to tell me what caused the balloon to become inflated. The balloon was filled with more air, so it got inflated.)

6(b) What caused this change?
The air in the glass bottle gained heat. It expanded and rose up into the balloon.
(You need to tell me how it got inflated. The air gained heat=>results in expansion=> air rose up => cause balloon to become inflated.)

Key learning point from this experiment:
Liquids and gases expand when they gain heat and contract when they lose heat.

Take note: Read the question very carefully. Highlight the keywords before doing the questions.
